What I meant was that for Broadway insiders, we know the names. Nancy is the type of role where it gives an unknown a chance to be discovered.
I was at a meeting a few months ago for a new New York production. The leading name was secured and they were discussing featured roles. It literally went "we can get Kristin or Audra for this role and Karen or Bebe or Charlotte for that role." Nothing wrong with using these talents, but I hate how they don't even open up the roles for unknowns (for the record, they did of course hold EPAs for the roles but still ended up casting who they wanted. This business truly IS
who you know.)
"The Spectacle has, indeed, an emotional attraction of its own, but, of all the parts, it is the least artistic, and connected least with the art of poetry. For the power of Tragedy, we may be sure, is felt even apart from representation and actors. Besides, the production of spectacular effects depends more on the art of the stage machinist than on that of the poet."
